Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43841   clinical trials with a EudraCT protocol, of which   7281   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Coronary Microvascular Dysfunction (CMD). In CMD, ischemia is caused by impaired endothelial and/or non-endothelial coronary vasoreactivity resulting in the coronary microvasculature not dilating properly or becoming vasospastic.
    E.1.1.1Medical condition in easily understood language
    In coronary microvascular dysfunction (CMD), the small vessels that provide blood and oxygen to the heart muscle do not function properly. In some cases they cannot relax, in other cases they spasm.
    Bij patiënten met CMD functioneren de kleine kransslagaders die de hartspier van bloed voorzien niet goed. Soms kunnen de vaten zich niet goed ontspannen, of soms verkrampen ze juist.
